Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world’s first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads. Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter! If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders. Lightmatter is (re)inventing the future of computing with light! About the role Lightmatter builds chips that enable extreme-scale artificial intelligence computing clusters. Join a multidisciplinary team to pioneer the future of computing by building the world's most advanced communications lasers. In this role you will help build the control plane and diagnostics software behind next-generation photonic interconnect products - implementing laser control and stabilization routines, the telemetry and monitoring firmware that keeps them healthy in the field, and the tooling that brings new hardware to life. You will work shoulder-to-shoulder with photonic, analog, digital, and systems engineers, own well-defined pieces of the stack end to end, and grow your depth in a domain where very few engineers have experience.
